A frame for resiliently supporting an individual relative to a ground surface. The inventive device includes an elongated main frame member having a steering tube mounted to a first end and a rear fork pivotally mounted to a second end thereof. A spring assembly extends between the main frame member and the rear fork to support the same in a collinear orientation. A pair of pivot pins extend through the main frame member to pivotally couple the rear fork thereto, the second pivot pin supports a guide pulley which directs a drive chain relative to the rear fork to permit articulation of the rear fork without interference with the chain.
